To all ickofiiiit Be it known";t at I, Banmu' lioa'ron,

subject of the Kinggf Great Brita-ii, residing at Melbourne ouse, Worcester-"Bo \Vorcester Englan have .inventedm-new and useful in rovement in Conveyers; a'i 1d I do hereby eclare.the following to, be a full, clear, and exact description of the same.

My invention comprises improvements in conveyors or screens and refers to that cla of such in which there' are-a pair of troughs both in substantially the -sa1ne.h rizontal' .plane and both supported 'by'inclined' levers, '15the troughs being-so connected that the rising weight of one trough is assisted by the falling weight of another trough forv the purpose of mutually balancing such troughs, the object ofmy said invention being to rovidean improved and'more perfectly alanced conveyer than those heretofore provided.

. According to lily-present invention in a1 conveyer in which there are 'two troughs both supported by inclined levers I provide.

an extension on one or more of the levers, this extension being connected to the other trough or to a lever supporting said trough,

- so arranged that if onetroughis'recipro cated its movement is transmitted to the other trough; -all. being so arranged that when one trough is rising the other trough is falling the rising weight-of one trough being assisted by the falling weight of the other trough. The swinging levers for mounting both troughs are inclined in the same direction so that both troughs will convey in the 'same direction.

' the drawings: Figure 1' is a Beferring t side elevation o the conveyer constructed according to" one form of invention Fig. 2

In the accompanying drawi gs -at Figs. 1 and 2 the conveyor troughs A and H are shown as being supported by inclined levers B in well known manner and so arranged that when'the troughs are reciprocatcd they will convey fromleft to right as indicated by arrows on the drawings the conveying Being was e, in the .county c trough B' atright angles forming as it were two p seem... menu with a ris ng advance; *and falling. return. The swmgm lovers are so ported above the Patentedo t. 15,1912.

fulcra .C an are attache by a free joint 9' to the troughs at E. '--i Ac 'cording to my nventlon' continue Hone or more of these swmiglmg levers on to the op osite sideof" the lcrumas indicated'by',

or to a. swinging lever sulpporting this, trough by, a connecting link It will be;

I i ","this ex'ten 'SlOD B being connected to-the trough H obvious that'f when the trough A. is falling 'itwill .seek to 'raise the trough'H and vice versa when the trough is 'falling its weight 7 will assist raising the trough A, therising wei ht of one trough being thus assisted by the alling weight of the other one, the two troughsbinginutually balancing. In

this conveyer the whole of the carrying 7m movement takes place on'one side of a vertical line through the fulcra.

\ At. Fig. .3 I have shown a modified form of my invention applied to similarly supported being provi ed with an extensionbellcrank levers which are connected by a link B, the two troughs being mutually troughs, a su porting lever on each 3;:

balancingin manner described above/ As will be seen' the lever B is rcciprocated with the trough and moves through only a limited arc of a circle, the balancing relation between the-two troughs being unchanged throughout the, travel oi'the troughs.

' If desired in place of single troughs there may be several troughs one above the other in well known manner as shown by Figs. 4: and 5. 1 v

I wish it to be understood that by'-balanc-. ing I do not necessarily mean a perfect balance. I mean tending to balance in order to, reduce the effort required to actuate the conveyer or screen. Thus when I' use a weight this may be arranged to balancethe empty conveyer or. it may balance a convcyer with average load. When two conv'eyers are arranged to mutually balance I prefer to make the empty conveyors balance and they will then also balance with equal loads. I

-What I claim then is:

1. In a conveyer the combination of a pair of horizontally disposed troughs, a

series of'inclined pivoted levers supporting' an extension to one of said levers projecting
